1.2 Software InstallationMi-Calc2 was developed on a Windows Vista computer with most testing performed on a Windows XP system. However, Mi-Calc2 should properly function on Windows 2000 and higher systems. Since Mi-Calc2 is not very resource intensive, the application can run on PC’s with 250+ MHz. microprocessors and at least 256 MB of RAM . Since all reports all saved as pdf fi les, make sure Acrobat Reader (or similar utility) is also installed.

The software installation fi le (miSetup.msi) will likely be provided on a CD. To install the program, just double-click on the installation fi le and follow the prompts. When installation is complete, a shortcut icon will be placed on your Windows desktop. By default, the application installs at C:\Program Files\Mercury Instruments\MI Calculator. Run-out reports are stored at C:\Program Files\Mercury Instruments\MI Calculator\Reports. If at some point, a new version is to be installed, the old version must fi rst be uninstalled using the Add/Remove Programs function in the Control Panel.

1.3 Main Screen LayoutA typical MI-Calc2 main screen is shown below. Notice the main screen is generally divided into three areas; Left, Middle and Right, which are described on the following pages.

8 www.honeywell.com

1.3.1 Main Screen (Left)The Left portion of the main screen is generally divided into two areas. The upper-left area provides manufacturer, program name and version information. The lower-left area provides communication settings. These settings must be properly confi gured when running semi-automatic run-out tests. The three confi guration boxes are blank when the program is initially installed. Once confi gured, the settings are retained until changed by the user.

The three Com settings provided are:

Com Port: List of all Com ports available on your computer. If a TCI is to be tested, a virtual IrDA port must be created. The virtual Com port is identifi ed with “(IrDA)” to the right of the Com port number. The driver to create this virtual Com port is provided on the MasterLink installation CD

Baud Rate: Choices: 300, 600, 1200, 2400, 4800, 9600, 19200 and 38400. Select the baud rate that matches the instrument under test.

Access Code: Enter the instrument’s 5-digit access code, which is displayed as asterisks.

1.3.2 Main Screen (Middle)The middle portion of the main screen is also divided into two areas. The upper portion is for selecting a particular instrument during semi-automatic run-out tests, while the button in the lower portion is used to initiate a manual run-out test.

To start a semi-automatic run-out test, double-click on the instrument icon that matches the instrument type being tested. If all of the Com settings were properly confi gured, a serial link will be established after site information is provided in the Corrector Volume Test form.

Note; remember to press the push button on TCI’s to establish a serial connection.

To start a manual run-out test, single-click the Manual Volume button. Once the Manual Volume run-out form appears, enter information into the input fi elds. Start the data entry at upper-left corner and TAB (move) from one category to the next, going left to right and top to bottom.

1.4 Accuracy Run-out TestsThis section describes using the semi-automatic and manual accuracy tests. The semi-automatic test makes two separate serial connections to the Mercury Instrument volume corrector to fetch specifi c parameter values before producing the run-out report. For the manual run-out test, all parameters must be manually entered by the operator. The pdf reports from both methods look near identical.

1.4.1 Semi-automatic Run-out TestTo start a semi-automatic run-out test, double-click the instrument icon that matches the instrument type being tested. After the Corrector Volume Test pop-up appears (shown below), enter the Site Name and Operator Name, which will appear in the printed report.

A run-out test is basically comparing the instrument’s pressure and temperature readings to reference values obtained from secondary pressure and/or temperature measurement devices, entered by the operator. In addition, the run-out test computes and compares the corrected volume values produced from both sets of readings. Therefore, click the check-box for “Enter instrument gauge pressure & gauge temperature”, which will provide input fi elds later in the process.

In order to obtain a meaningful run-out test, it’s important the secondary measurement devices (pressure test gauge, electronic thermometer, etc.) be accurate and calibrated. In general, the secondary measurement devices should be more accurate than the volume corrector under test.

After Site Name and Operator Name are entered, click the Next button (or just press Enter since the Next button should have focus) to start a serial link to the instrument. On its fi rst pass, the beginning corrected volume readings, beginning uncorrected volume readings and other information are collected. Progress bars are provided to allow you to follow the serial activity.

12 www.honeywell.com

After the fi rst pass is complete, a pop-up for entering the Reference Pressure is provided, assuming the corrector is confi gured for live pressure factors at item 109. If the instrument is confi gured as a Temperature-only corrector, the fi rst pop-up following the serial link will be for Reference Temperature input.

Enter the Reference Pressure obtained from the secondary measurement device and click Next to proceed to a pop-up for entering Reference Temperature.

Unless the instrument is confi gured as a Pressure-only corrector, a pop-up for entering the Reference Temperature will appear. Enter the Reference Temperature obtained from the secondary measurement device and click Next to proceed to a pop-up for entering volume.

13

After values for pressure and/or temperature are entered, some amount of volume must be applied to the meter and information about the number of meter turns must be entered.

Semi-automatic run-out tests can be used on the following three types of corrector/meter installations;

a) Mercury corrector with UMB / gas meter with I.D. (Instrument Drive)b) Mercury corrector with direct-mount to a rotary gas meter c) Remote-mount Mercury corrector with volume pulses transmitted from the gas meter

When the pop-up for inputting meter volume appears (shown below), there are two acceptable entry methods;

1) type in a numeric value at “Number of Turns:” and press Next (preferred)2) leave the “Number of Turns:” fi eld blank and press Next

The table below indicates which Mercury correctors are compatible with the three types of meter installations and whether or not it’s OK to leave the input fi eld blank before pressing Next. For EC-AT and Mercor Mini, the combination of meter drive rate and uncorrected volume with a different unit of measure requires a specifi c number of meter turns to occur before pressing Next. MI-Calc2 provides a value in the pop-in to inform you as to how many meter turns are required. It is important that the exact number of meter turns be honored since the accuracy calculations are based on this specifi c uncorrected volume.

UMB-mounted Direct-mount OK to Requires corrector corrector leave exact # (meter w/ I.D.) (meter w/o I.D.) blank of meter turns EC-AT X Yes Mercor Mini X Yes Mini-AT X X No Mini-Max X X No Mini-Max Rotary Corrector X X No TCI X X No

When entering the number of meter turns, instruments with designator “Yes” (from the above table) must have the exact number entered as indicated by the MI-Calc2 pop-up. Instruments with a designator “No” may enter any value of meter turns since these instruments incorporate a ‘Hi-Res UncVol’ function. (Mini-AT requires fi rmware version 6.90 or higher to be compatible.) Also, TCI and Rotary Correctors require a specialized meter-substitution calibration box to supply an exact (use supplied) number of meter turns to the instrument, which is also the value entered into MI-Calc2.

Where corrector/meter combinations allow for it (mainly TCI), the reason to leave the Number of Turns blank before clicking on Next is to let MI-Calc2 compute an unspecifi ed difference between the beginning and ending uncorrected volume readings. In this case, MI-Calc2 will accept the difference in volume and proceed with the run-out tests, primarily to determine and display temperature accuracy.

14 www.honeywell.com

After clicking Next for “Number of Turns”, MI-Calc2 makes a second serial link to the instrument to fetch new volume readings. After a few seconds to calculate the results, a pdf run-out report appears on the computer screen. Run-out reports are also automatically saved to:

C:\Program Files\Mercury Instruments\MI Calculator\Reports.

The reports are automatically named by combining the following report elements:Site Name + report day + report month + report year + report hours/minutes

Example: ECAT Test April 22 #1_22-4-2010_0819.pdf

1.4.2 Manual Run-out TestTo start a manual run-out test, single-click the Manual Volume button. The Manual Volume form will appear, as shown on the next page. Default parameters values are provided the fi rst time the form is used. After its fi rst use, the form will save entries made during its last use. As with other forms inside MI-Calc2, the form updates on every entry, therefore, an “Enter” or “Calculate” button is not needed, or provided.

After all information is entered, click the Preview button to produce the pdf run-out report. The resulting report will look near-identical to the semi-automatic report, except for the lower left corner. The manual report provides “(Manual)” next to the application name and version number, while the semi-automatic report provides “(Serial)”. This ‘identifi er’ is provided to let viewers of the report know which method was used to create the report.
